GSD-441 PG2

PowerG Wireless Natural Gas (Methane) Detector

Installation Instructions

1. INTRODUCTION

The GSD-441 PG2 is a wireless PowerG two-way natural gas
(Methane) detector. The GSD-441 PG2 is a natural gas detector
designed to send an alarm when Methane gas is detected. The
detectors can be used in a house, apartment, caravan, mobile home
or yacht.

The detectors are powered by 220 VAC. An internal Lithium battery
is used for AC power failure reporting only (the battery does not
power the detector).

The detector can send the following messages to the alarm system
control panel: Gas alarm, gas sensor failure, AC power failure and
low battery voltage.

The GSD-441 PG2 is designed for wall mounting and should be
placed in a location where gas presence, for example leakage, is
probable.

Upon gas detection, an audible buzzer is sounded and the built-in
transmitter transmits a digital message, composed of the detector's
PowerG ID followed by status messages. Alarm and other data are
thus forwarded to the alarm system. A periodic supervision
message is transmitted automatically (see specifications) to inform
the alarm system at regular intervals, of the unit’s active
participation in the system.

2. INSTALLATION

2.1 Preparing the Installation

A. The GSD-441 PG2 gas detector plugs directly into a standard 220VAC household switchable outlet (by a switch or circuit breaker).

Note: The installation must comply with the local authority electrical standards.

B. The ventilation slots must not be blocked and the unit must be kept free of dust.
C. A proper airflow must be maintained through the unit to obtain an air sampling of that area of the house where the sensor is situated.
D. The unit must be installed at least three feet from any gas appliance to eliminate false alarms but should not be placed over

20 feet from such appliances.

E. Install the unit away from any sources of vapor such as alcohol, liquor, vehicle exhaust, hair spray, cleaning agents, deodorants, paint,

fluorocarbons, or industrial solvents because vapors from these substances will trigger false alarms.

F. Do not install the unit directly above cooking appliances, directly above a sink, or adjacent to extractor fans.

Important!

 When the alarm sounds, immediately find out the cause and remedy it or evacuate the building
 Ventilate the area by opening doors and windows
 Immediately extinguish any flames or pilot lights
 Do not operate any electrical devices
 Determine the source of the gas. Seek a qualified technician or call your local gas company
